Primary Hypertension- Causes and Symptoms

Primary hypertension is the essential variety of hypertension. It is characterized by the fact that no medical cause can be found to explain the condition of a patient. The truth is that close to 95 per cent reported cases of hypertension are a result of essential hypertension.

No Causes Of Hypertension- Is That Possible?
The answer to the above question is "Only by definition." In reality there are a few identifiable risk factors which result in the development of primary hypertension. They are as follows:

Insulin Resistance: Insulin is a hormone secreted by the pancreas gland and is mainly responsible for facilitating the absorption of glucose in to the blood stream. However, it can also show vasodilatory properties. Hypertension can occur especially if somebody is suffering from insulin resistance and/or hyperinsulinemia.

Sodium sensitivity: This risk factor can be classified as environmental factor. It has been observed that a third of the population suffering from primary hypertension is sodium sensitive; arterial pressure rapidly increases whenever their salt intake increases. Though reducing salt intake has an effect on hypertension, the magnitude of the impact is too less to be recommended as a method of treatment.

Obesity: It has been pointed out that the risk of hypertension increases by five times if a person is overweight. People with Body Mass Index (BMI) more than 25 are considered to be highly prone to developing hypertension.

Role of Renin: Renin is an enzyme secreted by the kidneys. Its presence in the body is indicative of whether a person is suffering from high blood pressure or not. People with hypertension show more renin activity than those who have normal blood pressure levels.

Role of Genetics: It has been pointed out that one of the many causes of primary hypertension can be coded information inside one's genes. Close to 50 genes have been identified that can cause hypertension. Chief amongst them is the genetic code angiotensinogen (AGT).

Despite these findings, the conclusions are only indicative and further research needs to be carried out in order to establish a link between genetic codes and hypertension. However, those who have a family history of hypertension without any specific identifiable cause still face the risk of developing hypertension in their life.

Impact of Vitamin D: Recent studies have also suggested that deficiency of Vitamin D can have a negative impact upon cardiovascular health of an individual. Those found with Vitamin D deficiency were found with higher reading levels of diastolic and systolic blood pressure readings. The cause was found to be higher secretion levels of renin, in which Vitamin D played an important role. Increasing the amount of Vitamin D consumed can help correct levels of renin.
